The Liberty Pro680-series duplex grinder pump packages are compact systems designed for use in residential or light commercial sewage applications. These packages are ideal for basement bathroom additions and remodeling projects.

Each unit includes a 24″/46 gallon capacity polyethylene basin, two ProVore grinder pumps, and a duplex pump controller (indoor and outdoor models available). The extra capacity provides for longer and more efficient pump cycles while the shallow dimensions allow for easier installation in difficult soil or bedrock locations. The system can be installed above or below floor level with the two pumps providing secure and uninterrupted service for your system. A secure 16 bolt cover comes standard on all models; each cover can pass a 10′ stack test and also includes heavy-duty integrated rubber gaskets. An internal schedule 80 PVC discharge pipe is included as well.

Other key features: integrally molded no-hub 4″ inlet, a vent connection, integrated cord seal technology, integrally molded anti-flotation collar, integrally molded torque stops to keep the pumps in place and the Liberty patented QuickTree removable float technology. The QuickTree system allows easy access and removal of the switches without disturbing the plumbing or pump.

Units come completely assembled from the Liberty factory.
